A qualitative variable is a variable that cannot be measured in numerical terms, but rather, is characterized by qualities or attributes that are not numerical. Option A is the correct answer.

Qualitative variables are also called categorical variables because they represent categories or groups. Examples of qualitative variables include gender, nationality, religion, and occupation.

In contrast, quantitative variables can be measured in numerical terms, such as age, height, weight, income, and test scores. Understanding the nature and characteristics of different types of variables is important for selecting appropriate statistical methods and techniques to analyze and interpret data.

Answer:

VX = 8.8 in

Step-by-step explanation:

By applying Sine rule in the right triangle WXV,

Sin(∠W) = \(\frac{\text{Opposite side}}{\text{Hypotenuse}}\)

             = \(\frac{\text{VX}}{\text{WX}}\)

Sin(34)° = \(\frac{VX}{15}\)

VX = 15.Sin(34)°

     = 8.8379

     ≈ 8.8 in.

Therefore, measure of side VX is 8.8 in.

The equation of line p is y = ax + b then y = -2ax + b + 3 could be only the equation of line q out of the given options.

Therefore, the answer is C) y = -2ax + b + 3.

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. So in case of line p, a is the slope and b is the y-intercept. Let equation of q by y = m'x + b'.

From the figure it is evident that line p has a positive slope while line q has a negative slope. So slope of q is negative of slope of line q multiplied by a positive constant, say c, then

m' = -2ac

From figure we can observe that y-intercept of p is 0 and q has a positive y-intercept, so

b' = b + k, k is a positive constant

So equation of q is y = -2acx + b + k, where c and k are positive constants. So only option C is of this format.

--The question is incomplete, answering to the question below--

The total present value of these payments at the time the first payment is made is 1,735.85 (747.26 + 988.59).

To calculate the present value of these payments, we need to use the formula for the present value of an annuity:

\(PV = (P/i) x [1 - (1+i)^-n]\)

Where:
P = payment amount
i = annual effective rate
n = number of payments

Using this formula, we can calculate the present value of the first 10 payments:

\(PV = (100/0.07) x [1 - (1+0.07)^-10] = 747.26\)

To calculate the present value of the remaining 10 payments, we need to first calculate the payment amounts. To do

this, we can use the following formula:

\(Pn = P1 x (1 + g)^n\)

Where:
Pn = payment in year n
P1 = first payment amount
g = growth rate
n = number of years since first payment

For the 11th payment:

\(P11 = 105 x (1 + 0.05)^1 = 110.25\)

For the 12th payment:

\(P12 = 110.25 x (1 + 0.05)^1 = 115.76\)

And so on, until the 20th payment:

\(P20 = 163.32 x (1 - 0.05)^8 = 79.24\)

Now we can calculate the present value of these payments:

PV = \((110.25/0.07) x [1 - (1+0.07)^-10] + (115.76/0.07) x [1 - (1+0.07)^-9] + ... + (79.24/0.07) x [1 - (1+0.07)^-1]\)

PV = 988.59

Answer:

The numbers are 36 and 68.

Step-by-step explanation:

Let the smaller number be x.

"The larger number is four less than two times the smaller

number."

The larger number is

2x - 4

The sum of the numbers is x + 2x - 4, or 3x - 4.

"The sum of the numbers is 104."

3x - 4 = 104

3x = 108

x = 36

The smaller number is 36.

The larger number is 2x - 4, or

2x - 4 = 2(36) - 4 = 72 - 4 = 68

The larger number is 68.

Let's solve this using our formula for exponential functions:

\(y=a(b)^x\) where a is the initial value and b is the growth/decay rate. We will fill that equation in with 2 of the coordinates on the graph and come up with the values for both a and b. (0, 3) and (1, 6):

\(3=a(b)^0\). Anything raised to the power of 0 is 1, so that means that

a = 3. We will use that value along with the x and y from the second coordinate to solve for b:

\(6=3(b)^1\). b to the first is just b, so our equation is

6 = 3b and

b = 2.

Our equation then is

\(y=3(2)^x\), the third choice down.

The exponential value function is y = 3 ( 2 )ˣ

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the exponential function be represented as A

Now , the value of A is

y = 3 ( 2 )ˣ

when x = 0

y = 3 ( 2 )⁰

y = 3

when x = 1

y = 3 ( 2 )

y = 6

So , the points on the graph are ( 0 , 3 ) and ( 1 , 6 )

Hence , the function is y = 3 ( 2 )ˣ

The value of x and y between the parallel lines in both the parts are 71°, 109° and 65°, 115°

Two line are called parallel when they do not meet or intersect to infinity.

Using the concept of consecutive angles between parallel lines, we know that consecutive angles between the parallel lines are supplementary,

1) y = 109°  (vertically opposite angles)

x+109° =180° (Using the concept of consecutive angles)

x = 71°

2) y+65° = 180° (linear pair)

y = 115°

x+y = 180°

x = 180°-115°

x = 65°

Hence, the value of x and y in both the parts are 71°, 109° and 65°, 115°

The best comment Khalid could make to Salma about her opinion of the models she follows on social media is: "You don't need to be like those models to be happy." (Option C).

The chosen comment above comment is determined to be the best because it offers a constructive and positive perspective to Salma, while acknowledging her desire to emulate the models she follows on social media. It encourages her to shift her focus away from comparing herself to others and towards finding her own path to happiness.

The other options, such as "Models actually have amazingly hard lives" and "Those models actually aren't that attractive," are not helpful or constructive comments. They either discredit the hard work and dedication that models put into their careers or offer a negative perspective on their physical appearance. These comments are unlikely to make Salma feel better about herself or improve her outlook on the situation.

The comment "These models are probably selfish and vain people" is also not helpful because it makes an assumption about the models' personalities based solely on their social media presence, which is not necessarily accurate or fair.
